I see a future where the journalist gives the LLM two sentences and asks it to spit out a 2000 word article out of that.
The user then asks the LLM to Tl;Dr the article down to the two core sentences.
Same probably for business email. Jane goes "send an email to Joe saying no." The LLM goes "dear joe.. we appreciate.... your valuable conteibution.. unfortunately at this time... cannot consider... looking forward... thanks for .... whatever". Joe then clicks the "summarise" button and gets "Jane says no".
